CEL on after spark plug change???

So i just completed changing my spark plugs and to my surprise, my CEL came on after i fired her up. Also, she started to shake a lot more than ususal and it seemed like it was misfiring. So I went back under the hood to re-check my work and low and behold, i forgot to put on one of the wire harnesses! So i plugged it back in and now the shaking is gone but my CEL is still on.

Here are my concerns:
Did i do any major damage?
Can i reset my CEL myself?
Do i need to take it to the dealership to reset it or get my engine retuned?

Thanks in advance!

I think if you disconnect the battery for 15-20 seconds you'll be fine.

If disconnecting the battery does not reset the light, it should go out with 3 or 4 days of normal driving. This is providing that the problem is fixed. Make sure you do not drive it if the CEL is flashing. Also, AutoZone may reset the light for you at no charge.
